DOMESTIC HEATER.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed March 10, 1921. Serial No. 451,380.

To all whom it may concern:

Be it known that I, JosErH H. STETTNER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Domestic Heaters, of which the following is a specification.

In domestic warming appliances a vast amount of waste is occasioned by the use of heaters having flues. Such heaters require the continuous consumption of fuel. The object of the present invention is to provide a heater in which the fuel is consumed for a short time and the heat conserved for slow radiation to the room.

The invention is embodied in the construc tion herein shown and described the feature of novelty being finally claimed.

In the accompanying drawing- Figure l is a view in front elevation.

Fig. 2 is a vertical section on the line II-H Fig. 1.

In the views 5 designates a hollow body or receptacle of porcelain or fire clay having a glazed or smooth exterior surface adapted to carry away heat slowly, and 6 designates a cover for the receptacle such cover being of the same material and also having a. glazed or smooth exterior. In practice the receptacle is filled and packed with raw clay, and the cover cemented in its place. An advantage of making the receptacle in the form described is that the device may be transported economically and filled at the place of use.

The receptacle is supported upon a base constructed of glazed tile cemented together to form a fire chamber 8. Supported removably upon suitable brackets or projections 9 within the fire chamber is a heavy slab of soapstone 10 and below said slab extends a burner 11 receiving gas from a pipe 12 having an ordinary controlling valve 13. At its front side the fire chamber is provided with an opening closed with a. thick door 14 hinged at 15, said door being of a material that is a poor conductor of heat. The door can be porcelain and equipped with a latch 16 to engage an inclined hook 17 on the base so that the door may be pressed into air-tight engagement with the ja-mb of the opening.

In practice the stone slab will be rapidly and intensely heated, the door being left sufficiently open to permit fuel combustion, the door will then be closed and the gas turned off. The heat from the stone will be slowly and gradually absorbed by the mass of the structure and slowly radiated there from. An important advantage of this construction is that there are no flues or passages for the waste of products of combustion or of the heat, and further such a construction is adapted to thereby avoiding the necessity for the continuous consumption of fuel.

The form of the device may be varied without departing from the gist of the invention as claimed.

lVhat I claim is l. A heater comprising, in combination, a fiueless heat storing slow radiating body, a combustion chamber within said body, and a heat insulating door for air tightly closing said combustion chamber when the body has been heated.

2. A heater comprising, in combination, a flueless heat storing slow radiating body, a combustion chamber within said body, a slab of quickly heated material arranged in said chamber, a burner for heating said slab, and a heat insulating door for air tightly closing said combustion chamber when the body and slab have been heated.
